Hi Natalie
We have x/4 = 9
All you have to do is cross multiplication
x = 4*9
x= 36
That's all :)
I hope that's help:)
Now if you wanna check my answer just replace x by 36
36/4 = 9
9= 9
Because when you divide 36 by 4 you will find 9
I hope that's help:)
Step-by-step explanation:
If f(x) =x, is the father function, then all it's child function would be equally inclined to x and y-axis respectively.
Front yard
65+65+45+45=220
Back yard
45+45+35+35=160
220+160=380
380 feet
The proportion equal to a/b = c/d is A.) A/C = B/D
We will know if a proportion is equivalent when its cross products are equal.
a/b = c/d where ad = bc
since ad = bc, a/c = b/d
